NEW QUESTION 18
After a planned power outage, an administrator decided to restart the vSAN cluster manually.
What is the correct sequence of steps for the administrator to follow after powering on the ESXi hosts?

1. Enable cluster member updates from vCenter Server only on one ESXi host.
2. Run the python reboot helper script only on one ESXi host to recover the cluster.
3. Exit all hosts from maintenance mode.

1. Exit all hosts from maintenance mode.
2. Run the python reboot helper script only on one ESXi host to recover the cluster.
3. Enable cluster member updates from vCenter Server on all ESXi hosts.

1. Exit all hosts from maintenance mode.
2. Enable cluster member updates from vCenter Server only on one ESXi host.
3. Run the python reboot helper script only on one ESXi host to recover the cluster.

1. Enable cluster member updates from vCenter Server on all ESXi hosts.
2. Run the python reboot helper script on all ESXi hosts to recover the cluster.
3. Exit all hosts from maintenance mode.

Explanation
This is the sequence of steps recommended by VMware for manually restarting the vSAN cluster after a planned power outage. The steps are as follows:
Enable cluster member updates from vCenter Server only on one ESXi host. This will allow the host to receive the latest cluster membership information from vCenter Server and avoid any conflicts or inconsistencies with other hosts. The command to enable cluster member updates is esxcfg-advcfg -s 1
/VSAN/IgnoreClusterMemberListUpdates.
Run the python reboot helper script only on one ESXi host to recover the cluster. This will prepare the cluster for a manual restart by partitioning the cluster and ensuring that all hosts have consistent metadata. The command to run the python reboot helper script is python
/usr/lib/vmware/vsan/bin/reboot_helper.py prepare.
Exit all hosts from maintenance mode. This will allow the hosts to resume normal operations and join the vSAN cluster. The command to exit maintenance mode is esxcli system maintenanceMode set -e false.
The other options are incorrect for the following reasons:
B, exit all hosts from maintenance mode, run the python reboot helper script only on one ESXi host to recover the cluster, and enable cluster member updates from vCenter Server on all ESXi hosts, is incorrect because exiting all hosts from maintenance mode before running the python reboot helper script can cause data inconsistency or corruption, as the hosts may not have the latest metadata or cluster membership information. Enabling cluster member updates from vCenter Server on all ESXi hosts is also unnecessary and can cause conflicts or inconsistencies with other hosts.
C, exit all hosts from maintenance mode, enable cluster member updates from vCenter Server only on one ESXi host, and run the python reboot helper script only on one ESXi host to recover the cluster, is incorrect because exiting all hosts from maintenance mode before running the python reboot helper script can cause data inconsistency or corruption, as the hosts may not have the latest metadata or cluster membership information.
D, enable cluster member updates from vCenter Server on all ESXi hosts, run the python reboot helper script on all ESXi hosts to recover the cluster, and exit all hosts from maintenance mode, is incorrect because enabling cluster member updates from vCenter Server on all ESXi hosts is unnecessary and can causeconflicts or inconsistencies with other hosts. Running the python reboot helper script on all ESXi hosts concurrently can also cause a race condition that can result in unexpected outcomes.

NEW QUESTION 19
A vSAN administrator has a cluster configured with a Storage Pool that was moved to a new physical DC.
Upon checking on the vSAN cluster health status, one of the ESXi hosts has two storage devices in a degraded state and must be replaced.
What must the vSAN administrator do to restore the health of the vSAN cluster with minimum risk?

Remove the host from ySAN configuration, replace the faulty disks, re-create the storage pool

Remove the entire storage pool, install the new devices, re-create the storage pool

Remove the host from the cluster, replace the faulty disks, re-add the host to the cluster

Remove the devices from the storage pool, replace the storage devices, claim the new devices in vSAN

NEW QUESTION 20
The Resyncing Objects view in the vCenter UI reports that some objects are currently resyncing.
Which two actions would cause this situation? (Choose two.)

A change to the storage policy is applied to the objects.

DRS is relocatingVMs between vSAN nodes.

A host failure occurs in the cluster

HA Virtual Machine Monitoring forced a VM to reboot.

VM snapshot is being deleted.

NEW QUESTION 21
An existing vSAN OSA cluster has this specification:
Four ESXi hosts with all flash configuration
Each with two disk groups
Each disk group with one cache device and four capacity devices
There are five more device slots available per host
The CTO would like to provision new applications, and these will need more capacity and performance.
Which two methods should be used by the vSAN administrator to meet this goal with the least amount of impact? (Choose two.)

Replacing all capacity devices with a similar larger device

Replacing all cache devices with a larger device

Adding one more disk group per host with the same configuration

Adding faster cache devices

Adding an ESXi host with identical device configuration

Explanation
Adding one more disk group per host with the same configuration and adding an ESXi host with identical device configuration are the two methods that the vSAN administrator should use to meet the goal of increasing capacity and performance with the least amount of impact. Adding one more disk group per host will increase the raw storage capacity by 20% and also improve the performance by distributing the I/O load across more cache devices and disk groups. Adding an ESXi host with identical device configuration will increase the raw storage capacity by 25% and also improve the performance by adding more compute and network resources to the cluster. Both methods can be done without disrupting any ongoing operations or requiring any data evacuation or resynchronization.
The other options are incorrect for the following reasons:
Replacing all capacity devices with a similar larger device is incorrect because it will not increase the performance and will have a significant impact on the cluster. Replacing the capacity devices requires deleting the disk groups, which will erase all data on them and trigger a resynchronization of the affected objects. This can be disruptive and time-consuming, and also introduce additional network and disk traffic.
Replacing all cache devices with a larger device is incorrect because it will not increase the capacity and will have a significant impact on the cluster. Replacing the cache devices also requires deleting the disk groups, which will have the same drawbacks as replacing the capacity devices. Moreover, increasing the cache size may not improve the performance significantly, as vSAN OSA uses afixed cache ratio of
70% for write buffer and 30% for read cache, regardless of the cache device size.
Adding faster cache devices is incorrect because it will not increase the capacity and will have a significant impact on the cluster. Adding faster cache devices also requires deleting the disk groups, which will have the same drawbacks as replacing the cache devices. Furthermore, adding faster cache devices may not improve the performance significantly, as vSAN OSA uses a fixed cache ratio of 70% for write buffer and 30% for read cache, regardless of the cache device speed.

NEW QUESTION 24
A customer wishes to host a new range of applications with high-performance requirements, specifically, low latency. The current vSAN platform is based on ReadyNode hardware and uses a vSAN 7.0 U2 hybrid topology configuration.
Which would satisfy the customer’s requirement?

Deploy the application on a new cluster with vSAN 8.0 ESA using a new hardware design

Deploy the new applications on the existing cluster with a RAID-6 VM storage policy and an additional stripe width of 4

Deploy the application on a new cluster with vSAN 8.0 OSA using the existing hybrid configuration

Perform an in-place upgrade from vSAN 7.0 U2 OSA to vSAN 8.0 ESA

Explanation
Deploying the application on a new cluster with vSAN 8.0 ESA using a new hardware design is the correct answer because it will satisfy the customer’s requirement for low latency. vSAN 8.0 ESA is a new architecture that uses a storage pool configuration where all disks are treated as capacity disks and use a new algorithm to distribute data across them. This improves the I/O flow, reduces the write amplification, and eliminates the cache tier bottleneck. Using a new hardware design with all-flash disks or NVMe disks will further enhance the performance and latency of the application, as these disks have faster read and write speeds than hybrid disks. Deploying the new applications on the existing cluster with a RAID-6 VM storage policy and an additionalstripe width of 4, deploying the application on a new cluster with vSAN 8.0 OSA using the existing hybrid configuration, and performing an in-place upgrade from vSAN 7.0 U2 OSA to vSAN 8.0 ESA are not valid or optimal solutions for this scenario. Deploying the new applications on the existing cluster with a RAID-6 VM storage policy and an additional stripe width of 4 will increase the resiliency and availability of the data, but it will also increase the network traffic, disk space consumption, and parity calculation overhead, which will negatively affect the latency and performance of the application. Deploying the application on a new cluster with vSAN 8.0 OSA using the existing hybrid configuration will not improve the latency significantly, as vSAN 8.0 OSA still uses the same disk group configuration as vSAN 7.0 U2 OSA, where one disk is designated as a cache disk and the rest are capacity disks. The cache disk can still become a bottleneck for high-performance applications, especially if it is not an SSD or NVMe disk. Performing an in-place upgrade from vSAN 7.0 U2 OSA to vSAN 8.0 ESA is not possible, as vSAN ESA requires a different hardware design than vSAN OSA. The existing disk groups need to be deleted and all disks need to be erased before switching to vSAN ESA. References:

NEW QUESTION 25
A site administrator wishes to implement HCI mesh between two clusters on vSAN that are located in geographically separate sites and which are administered within a single datacenter.
Which two requirements should the vSAN administrator consider to accomplish this goal? (Choose two.)

Either Layer 2 or Layer 3 communications can be used

A leaf spine topology is required for core redundancy and reduced latency

NIC teaming must be implemented for the vSAN network vmkernel port

The configuration must meet the same latency and bandwidth requirement as local vSAN

Encryption must be disabled prior to configuring HCI mesh

NEW QUESTION 26

NEW QUESTION 27
A three-node vSAN OSA cluster with business critical intensive I/O workload is running out of capacity. Each host consists of five disk groups with four capacity disks. The administrator needs to expand the capacity of the vSAN datastore as soon as possible.
What should the administrator do?

Enable Deduplication and Compression on the cluster level

Add additional capacity by adding a disk on one host and creating a storage pool

Add additional capacity by addinga vSAN ReadyNode to the cluster

Add additional capacity disks to each disk group

Explanation
The correct answer is D, add additional capacity disks to each disk group. This is because adding capacity disks to existing disk groups is the fastest and easiest way to expand the capacity of the vSAN datastore without disrupting any ongoing operations or requiring additional hardware. The administrator can add up to five capacity disks per disk group in vSAN OSA, which means each host can have up to 25 capacity disks in total. The administrator should make sure that the new capacity disks are unformatted and not partitioned, so that vSAN can recognize and claim them. The administrator should also manually rebalance the cluster after adding the capacity disks to distribute the data evenly across the new devices. The other options are incorrect for the following reasons:
A, enable Deduplication and Compression on the cluster level, is incorrect because enabling Deduplication and Compression is not a recommended way to expand the capacity of the vSAN datastore. Deduplication and Compression is a space efficiency feature that reduces the logical space consumption of data by eliminating duplicate blocks and applying compression algorithms. However, enabling Deduplication and Compression requires a full data evacuation and resynchronization, which can be disruptive and time-consuming. Deduplication and Compression also introduces additional CPU and memory overhead, which can affect the performance of the cluster. Deduplication and Compression is only supported on all-flash clusters, not on hybrid clusters.
B, add additional capacity by adding a disk on one host and creating a storage pool, is incorrect because creating a storage pool is not supported in vSAN OSA. A storage pool is a new configuration introduced in vSAN 8 ESA, where all disks are treated as capacity disks and use a new algorithm to distribute data acrossthem. This configuration is not compatible with vSAN OSA, which uses a disk group configuration where one disk is designated as a cache disk and the rest are capacity disks. To use a storage pool, the administrator would need to migrate to vSAN 8 ESA on a new cluster with new hardware.
C, add additional capacity by adding a vSAN ReadyNode to the cluster, is incorrect because adding a vSAN ReadyNode to the cluster is not the fastest or easiest way to expand the capacity of the vSAN datastore. A vSAN ReadyNode is a preconfigured server that meets the hardware requirements for running vSAN. Adding a vSAN ReadyNode to the cluster would require additional hardware procurement, installation, and configuration. It would also increase the compute capacity of the cluster, which may not be necessary for the workload. Adding a vSAN ReadyNode would also trigger a resynchronization of data across the cluster, which can affect the performance and availability of the cluster. References:

Which vSAN feature should be used for this purpose?

vSAN File Services

vSAN HCI Mesh

vSAN Replication

vSAN Stretched Clusters

NEW QUESTION 29

NEW QUESTION 30
A vSAN administrator has recently upgraded a vSAN cluster to 8.0 OSA and has enabled Capacity Reserve features to reduce the amount of capacity reserved for transient and rebuild operations.
Which scenario would prevent this feature from operating properly?

Underutilized space is above 25-30% of the total capacity threshold.

The used space on vSAN datastore exceeds the suggested host rebuild threshold.

The used space on vSAN datastore exceeds the suggested slack rebuild threshold.

The physical disk has reached an 80% full reactive rebalance threshold.

NEW QUESTION 31
